Sorry, garbage.

Explanation attempt number 2, now based on added debug output:

mod_filter does not get the response output headers, if the request is
handled by a CGI. The headers are in err_headers_out, but not in
headers_out. Thus any attempt to match via resp=... must fail. But
that's what is tested in the failing test case.

If I reverse proxy the request and run the CGI on the origin server, the
headers are there and the test succeeds.

Is this a known bug? Should I open an issue?

... and it is only a problem for 2.2.x. For 2.3 Joe enhanced the
expression parser in r1090234 to also look at err_headers_out. So for
trunk it works and it seems the problem was well know.
